本論文主要模擬視流測試馬達帶動真實引擎與靜態汽缸缸內紊流流場，其中靜態汽缸缸內紊流流場又可分為穩態具活塞側向排氣與穩態不具活塞下方排氣兩種。主要目的在評估較容易測試之靜態排氣裝置取代馬達帶動真實引擎的可行性與流場相似性。
研究方法之一是使用美國Los Alamos國家實驗室所發展出來的KIVA-3V Release 2三維數值模擬原始程式，並依照本論文的需求加以局部修改並在個人電腦上進行。模擬比較的基本狀態為實驗引擎進氣閥開度為3mm、5mm及7mm時之缸內流場。方法之二為利用視流實驗拍攝透明汽缸內流場，並與數值模擬結果作一比對。本研究目的即針對以靜態排氣來代替馬達帶動真實引擎之可行性與活塞面的存在對靜態進氣階段汽缸內流場的影響做一探討。並對無活塞的靜態流場、具活塞面之靜態流場及非靜態的馬達帶動真實引擎三者的流場作一比較，探討汽缸內流場細部的變化情形，包括速度場、紊流動能及流體徑線圖等。

模擬結果顯示靜態不具活塞下方排氣裝置汽缸內的流場可以反映出馬達帶動真實引擎的主要流場趨勢；而側向排氣裝置由於加裝了側向排氣管，雖然會對原本的流場造成些許破壞，但在近活塞面的位置上側向排氣裝置汽缸內的流場會因活塞面的影響與非靜態馬達帶動真實引擎有相同的趨勢。而以視流法所拍攝的流場與數值模擬的結果相互契合，也應證了以KIVA-3V數值流力模擬汽缸流場的準確性。
